NRCS Aquatic Organism Passage - 396Natural Resources Conservation Service Conservation Practice Job SheetWASHINGTON

September 2011

DefinitionModification or removal of barriers that restrict or impede movement or migration of fish or other aquatic organisms.

PurposesImprove or provide upstream and downstream passage for fish and other aquatic organisms.

Where UsedThis practice applies to all watercourses and outlets of ponds, lakes and wetlands where barriers impede passage for fish and other aquatic organisms.

Passage barriers can be natural (e.g., waterfalls, beaver dams) or artificial (e.g., road culverts, surface water diversions). Native fish have evolved around the presence of natural barriers – they should be left in place. Beaver dams, for example, may block weak-swimming fish at all flows or strong swimmers during only extreme flows, yet they create very diverse habitat for fish and numerous other species of aquatic and terrestrial wildlife.

Artificial barriers, on the other hand, should be completely removed or the stream should be rerouted

around them to avoid installing expensive, high-maintenance fishways (fish ladders). However, for some surface-water diversion dams or weirs, a fishway may be the only alternative. A concurrent “passage” problem at these diversion structures is the loss of fish that become entrained in the diverted flow. This problem is best addressed by installing screens, using Structure for Water Control (587).

Resource Management SystemThis practice is commonly applied concurrently with Practice 395 - Stream Habitat Improvement and Management as part of a resource management system for a conservation management unit.

Often, artificial barriers (especially culverts) are associated with unstable stream conditions. When this occurs, the Aquatic Organism Passage practice should be part of a long-range goal to restore geomorphic stability and habitat features to the stream by combining it other supporting practices such as Stream Habitat Improvement and Management, (395), Channel Stabilization (584), Streambank and Shoreline Protection (580) and others.

Washington Job Sheet – Aquatic Organism Passage (396) Page 1 of 11

Structures installed under this practice must be designed not only for upstream passage of organisms, but also for downstream passage of high flows, bedload, and instream wood material. The Washington Department of Fish and Wildlife (WDFW) requires that road crossings maintain their structural integrity during a 100-year flow event.

Fish Passage CriteriaThere are 48 native species of anadromous and resident fish that use Washington State streams. Their ability to negotiate instream obstructions varies by species and by size of individual fish within a species. This practice will follow the passage criteria already established by WDFW for the 8 native species of salmon and trout and may be further refined when criteria is set for the state’s 15 other migratory species. Also, additional criteria may be required by federal agencies for fish that are protected under the Endangered Species Act.

Operation and MaintenanceThis practice will be inspected periodically and restored as needed to maintain the stated purpose for passage.

Specify what entity is responsible for the daily operation and maintenance of a passage structure.

Check a passage structure at regular intervals to ensure it is operating within design criteria.

Clean trashracks and debris collectors or remove debris accumulations regularly.

Adjust gates, orifices, valves, or other control devices as needed to regulate flow and maintain a passage structure within operating criteria.

Periodically check staff gages or other flow metering devices for accuracy.

Annually inspect passage structures for structural integrity and disrepair.

Inspect gate and valve seals for damage.

Replace worn or broken stoplogs, baffles, fins, or other structural components.

Remove sediment accumulations from within passage structure where applicable.

Additional operation and maintenance requirements will be listed in individual Supporting Practices and within the construction design.

SpecificationsSite-specific requirements are listed on the Job Sheet with instructions for filling out the Job Sheet on the Specification. Additional specifications will be used for Aquatic Organism Passage from individual Supporting Practices and construction design.
